01 The rubber like elastic rubber is different from the elastic energy represented by the longitudinal elastic coefficient (Young's modulus). It refers to the so-called "rubber elasticity" that can be restored even for hundreds of percent deformation on the basis of the entropy elasticity generated by the contraction and spring off of the molecular lock. 02 Embodiment rubber

NR (Natural Rubber) is a polymer of isoprene, which is made from rubber latex collected from rubber trees. It has good wear resistance, high elasticity, breaking strength and elongation. It is easy to age in air and become sticky when exposed to heat. It is easy to expand and dissolve in mineral oil or gasoline. It is alkali resistant but not strong acid resistant. Advantages: good elasticity, acid and alkali resistance. Weatherproof,

Natural rubber (NR) is a kind of natural macromolecular compound with cis-1,4-polyisoprene as the main component. Among its components, 91%~94% are rubber hydrocarbons (cis-1,4-polyisoprene), and the rest are non rubber substances such as protein, fatty acid, ash, sugar, etc. Natural rubber is the most widely used general rubber. Generally speaking, natural rubber refers to

The spacing and elevation of rubber fenders are very important. It is necessary to ensure that the ship can not directly touch the quay wall under the most unfavorable berthing angle allowed by the specification. It is also necessary to ensure that the ship can safely berth at different tide levels and draughts, and has strong adaptability to the berthing of ships of different tonnage. When selecting and deciding the layout scheme of Phase I, II and III fenders of the coal terminal

For all kinds of articles in life, our feelings about them are intuitive, such as the concepts of hardness, elasticity, toughness, brittleness, etc. This information obtained through intuitive feeling and perception is generally called qualitative judgment. Qualitative judgment is usually vague, imprecise and not conducive to comparison. Just as we know that iron is hard and steel is hard, which one is harder, except for the two

Classification of rubber fenders; Features and applications Generally, rubber fenders can be divided into two categories according to their structures: solid rubber fenders (non floating) and floating rubber fenders. Solid rubber fender (non floating type) is an anti-collision equipment for ships in wharf with an early application history and a wide application range. According to the stress condition of rubber fenders, they can be divided into shear type, rotary type and compression type; root

The floating installation method of offshore platform topsides has become an effective installation method since the 1980s. After years of practice and exploration in the industry, not only the weight of the installation structure is increasing, but also the installation method is constantly challenging the worse construction sea conditions. The floating method solves the contradiction that the module construction cannot be expanded due to the limitation of lifting capacity, and improves the efficiency of platform construction

The float over method (float over installation method) is an installation technology that uses a barge to carry the topside of the offshore operation platform. During the installation process, the topside is lifted and lowered by means of tide level, barge load adjustment and lifting mechanism. At the same time, special connecting parts are used to complete the butt joint between the topside and the lower jacket platform. During the floating installation of offshore platform module, the module is loaded by tug
